Patients taking bromocriptine still have high prolactin, which is considered to be due to insufficient time of taking it. Generally, it takes more than 3 months to take bromocriptine for high prolactin to have an effect. Bromocriptine is a commonly used drug to treat elevated prolactin. Women with persistently high prolactin may experience menopausal symptoms, so it must be controlled in a timely manner. If you take bromocriptine for a long time, you may experience dizziness, nausea, loss of appetite and other side effects. If you take bromocriptine for a long time and your prolactin level continues to rise without improvement, you need to undergo CT examination to rule out the possibility of pituitary tumor.
